Modelling of Wi-Fi signal propagation using the boundary element method

Project reference: 1512

The main goal of this project is to develop a workflow for parallel modelling of the Wi-Fi signal propagation in buildings using the boundary element method (BEM). For this purpose the student will use the parallel boundary element software BEM4I developed at IT4Innovations National Supercomputing Centre. The student will go through all phases of numerical modelling. In the first stage of the project a 3D model of a building will be created using an appropriate meshing tool (e.g., MeshLab, Gmsh, NETGEN). Next, the BEM4I library will be used to simulate signal propagation. This simulation will be done in parallel using Anselm supercomputer located at IT4I. Finally, the result will be visualized using an external library, such as ParaView, Visit, or EnSight. During the stay the student will cooperate directly with developers of the BEM4I library and experts on meshing and visualization software.
